Assembly

u

Pull the plug out of the socket before cleaning or per-
forming maintenance on the vacuum cleaner, making
tool adjustments, changing accessories or putting
away the vacuum cleaner.

 This safety measure prevents

the vacuum cleaner from being started accidentally.

Fitting the vacuuming accessories (see figure A)

The vacuum hose 

(15)

 is equipped with a clip system which

can be used to connect vacuuming accessories (dust extrac-
tion adapter 

(16)

, curved nozzle 

(17)

).

Fitting the nozzles and tubes

– Push the curved nozzle 

(17)

 onto the vacuum hose 

(15)

until you hear both snap fasteners 

(27)

 on the vacuum

hose engage.

– Then attach the required extraction accessory (floor

nozzle, crevice nozzle, suction tube, etc.) firmly to the
curved nozzle 

(17)

.

– To remove the accessory, press the snap fasteners 

(27)

inwards and pull apart the components.

Fitting the dust extraction adapter

– Push the dust extraction adapter 

(16)

 onto the vacuum

hose 

(15)

 until you hear both snap fasteners 

(27)

 on the

vacuum hose engage.

– To remove the adapter, press the snap fasteners 

(27)

 in-

wards and pull apart the components.

Fitting the vacuum hose

Vacuuming function (see figure B1)

– Push the vacuum hose 

(15)

 into the hose connection

piece 

(3)

 and turn it as far as possible in the direction of

rotation  .

Note:

 The friction generated by the dust in the vacuum hose

and accessory during extraction causes an electrostatic
charge that the user may experience as static discharge (de-
pending on environmental factors and their physiological
state).
Bosch generally recommends using an anti-static vacuum
hose (accessory) to vacuum up fine dust and dry materials.

Blowing function (see figure B2)

u

The vacuum cleaner has a blowing function. Do not
blow exhaust air out into the open air. Only use the
blowing function with a clean hose.

 Dust can be hazard-

ous to health.

– Switch on the dust extractor for at least 5 seconds (mode

selector switch 

(1)

 set to the "extraction" symbol) to

clean the vacuum hose 

(15)

 of dust deposits.

– Turn the vacuum hose 

(15)

 as far as possible in the direc-

tion of rotation 

 and pull it out of the hose connection

piece 

(3)

.

– Push the vacuum hose 

(15)

 into the hose connection

piece 

(13)

 and turn it as far as possible in the direction of

rotation  .

Removing/Inserting the Pre-filter

The pre-filter 

(22)

 prevents coarse dirt from getting through

and consequently extends the lifetime of the main filter. The
pre-filter must be removed from the container if you intend
to carry out wet vacuuming or to clean the main filter.

Removing the Pre-filter (see figure D1)

– Open the catches 

(9)

 and remove the top part of the va-

cuum cleaner 

(10)

 (see figure 

C

).

– Remove the pre-filter 

(22)

 from the container 

(7)

.

Inserting the Pre-filter (see figure D2)

– Insert the pre-filter 

(22)

 in the container 

(7)

, making sure

that the arrows are pointing towards the hose connection
piece 

(3)

.

– Put the top part of the vacuum cleaner 

(10)

 on and close

the catches 

(9)

.

Removing/Inserting the Main Filter

The main filter 

(20)

 is a HEPA pleated filter with extremely

high filtration performance for cleaning exhaust air. You
need to remove the main filter from the container if you in-
tend to carry out wet vacuuming.

Removing the Main Filter (see figure E1)

– Open the catches 

(9)

 and remove the top part of the va-

cuum cleaner 

(10)

 (see figure 

C

).

– Turn the filter holder 

(28)

 as far as possible in the direc-

tion of rotation 

 and take the filter holder, together with

the main filter 

(20)

, out of the top part of the vacuum

cleaner 

(10)

.

Inserting the Main Filter (see figure E2)

– Place the filter holder 

(28)

, together with the main

filter 

(20)

, over the filter basket 

(29)

 and turn the filter

holder 

(28)

 as far as possible in the direction of rotation

.

– Put the top part of the vacuum cleaner 

(10)

 on and close

the catches 

(9)

.

Inserting/removing the wet filter

To make disposal easier when vacuuming water-solid mix-
tures, the vacuum cleaner has a wet filter 

(21)

 that separ-

ates the liquid from the solids.

Inserting the Wet Filter (see figure F1)

– Open the catches 

(9)

 and remove the top part of the va-

cuum cleaner 

(10)

 (see figure 

C

).
